Anniversary of Titanic discovery: Everything to know about the dive site

Rare Titanic footage released show state of the sunken ship

Rare video of the 1986 dive through the wreckage of the Titanic has been released for the first time. The Woods Hole Oceanographic Institution posted more than 80 minutes of video of the ocean liner that sunk in April of 1912.

Sunday marked the anniversary of the discovery of the site of Titanic’s wreckage at the bottom of the ocean floor.

The famous RMS Titanic sank in 1912, but the wreckage wasn’t discovered until nearly 75 years later, on Sept. 1, 1985.

A submersible that imploded in the North Atlantic while taking five people down to the Titanic last summer renewed interest in the famous shipwreck, as well as prompted questions regarding what it takes to reach the site 2.5 miles below the ocean’s surface.

Here is everything to know about the famous ship’s dive site:

What happened to the Titanic?

Titanic survivor and historian speaks on recovery efforts

ARCHIVE - Louise Pope, a Titanic survivor and historian, spoke in 1986 with FOX 9 in Milwaukee about the shipwreck after the site was discovered and recovery efforts began to bring items to the surface.

The ocean liner Titanic struck an iceberg and sank in April 1912, killing all but about 700 of the roughly 2,200 passengers and crew.

Since the wreckage’s discovery in 1985, it has been slowly succumbing to metal-eating bacteria. Some have predicted the ship could vanish in a matter of decades as holes yawn in the hull and sections disintegrate.

Where is the Titanic wreck?

The Titanic wreck site is located 963 miles northeast of New York and 453 miles southeast of the Newfoundland coastline, sitting 12,000 feet below sea level.

James Cameron Titanic dive

Filmmaker James Cameron is also a deep-sea explorer and has a well-known affinity for the doomed ship.

He famously made the 1997 film "Titanic," which became the highest-grossing film in history at the time, as well as earning 11 Academy Awards.

His interest in shipwrecks served as a motivation to make the film.

"I made Titanic because I wanted to dive to the shipwreck, not because I particularly wanted to make the movie," Cameron told Playboy Magazine in 2010. "The Titanic was the Mount Everest of shipwrecks, and as a diver I wanted to do it right."

Cameron made several submersible dives to the wreck itself prior to the movie’s release. He later formed Earthship Productions to make documentary films about ocean exploration and conservation.

In total, he has done 33 dives to the Titanic wreckage site since the film’s release, according to National Geographic.
